IMPROVEMENT IN FRUIT-JARS.

pecification forming part of Letters Patent No. 49,256, dated August 8,1865.

To all whom 'it' may concern:

Be it known that we, WiLLiAM T. GILLIN- DER and EDWIN BENNETT, of thecity and county of Philadelphia, and State of Pennsylvania, have made anew and useful Improvement in Fruit-Jars; and we do hereby declare thefollowing to be a full, clearand exact deferent figures.

-Our improvement consists of a grooved glass cover containing a ringofelastic material, which is pressed down upon and partially around theupper edge of the jar or bottle by means of the screw-cap.

To enable those skilled in this branch of manufacture to construct thesame, and to indicate the mode of using the same, we will proceed todescribe it.

A is a glass jar or bottle, which is a mere question of shape, and Bis aglass cover, which has an annular groove, C, on its lower face of such aconformation as to have two shoulders, D D, and a central depression, E,which agrees in its diameter with that of the upper projecting edge, F,of the jar. The upper exterior portion of the neck of the jar isprovided withthreads G G, whichcorrespond with those in the screw- `capH. The ring K, ofindia-rubber or other elastic substance, is laid withinthe groove C, upon the shoulders D D, and spanning the depression E, asshown in Fig. l.

The operation is as follows: The jar being filled with fruit in theproper manner, or to the satisfaction of the operator, the cover,containing the elastic annular pad within its groove, islaid upon theupper edge of the jar, and the screw-cap being placed over and rotatedis thereby drawn down with its iiange H upon its cover B, so as to pressthe latter down and compel the edge F to project the ring into thedepression E (see Fig. et) and embrace a portion of the sides of theflange F as well as its top. This makes the packing much more effective,as the bearing is more extensive, and

a leakage from the presence of a small flaw on the upper edge is not soimminent.

The bottle Vis unclosed bylsimply unscrewing the cap H and raising thecover. The general appearance of the jar when closed is neat andtasteful, and they1 may he readily wiped oifto remove the dust in thesale-room or the storeroom of the housewife, as well `as any drip whichhas fallen upon them in the actof filling. In this respect they contrastfavorablywith many wire-and-yoke devices `which are before the people.The elastic pad, when the cover is detached, remains within the grooveand does not require special manipulation to place it in 1 position, asthe shoulders and sides of the groove are in contact with it, and thusit is prevented from being lost, and great time is saved and accuracyattained by always compelling it to maintain its proper position withoutspecial manipulation to t it over the place it is to occupy.

Though not an absolute necessity, we prefer to have the elastic padoccupy the groove in` i the cover from the .shoulders outward, so as tomake them come ush with the lower face of the cover, which makes a neatfinish, and enables them to be readily wiped'otlbefore being placed incontact with the edibles in thejar.I

Having thus described our invention, we state that we do not claim,broadly, the use of a screw-cap, cover, and elastic ring; but

What we claim herein as new, and desire to secure by Letters Patent, is-

The formation of the groove in the cover,

with shoulders supporting the elastic pad, and with a central depressioninto whichV the pad is forced by the upper edge of the jar on thedownward pressure on the cover by the screwcap, substantially asdescribed.

To the above specification of our improvement in fruit-jars we havesigned our names this 29th day of April, 1865. y
